AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OHIO
258 AM EDT THU AUG 3 2006

.SHORT TERM (TODAY THRU FRIDAY)...
QUESTION TDA IS HOW FAR MORN OUTFLOW BOUNDARIES PROGRESS TO THE SSE
WHICH WL DETERMINE FOCUS FOR MIDDAY NEW CONVECTION. CERTAINTLY LOOKS
AS IF A PART OF NWRN CWA WL BE N OF THE BNDRY AND MAY BE SPARED FM
HVY RA AND SVR THREAT ASSUMING ONGOING STRONGER ACTIVITY OVR NRN IN
AND LWR MI CONTS TO WKN AS IT MOVS INTO NWRN PART OF OUR CWA. WL HV
TO WATCH TO ZONE ISSUE TIME TO DECIDE IF FLOOD WATCH MAY NEED
ADJUSTING TO ELIMINATE ANY OF THESE COS...BUT PROB WL LV AS IS FOR
CONSISTENCY PURPOSES. OTRW...WITH PW/S CLOSE TO TWO INCHES AND GND
MSTR HI IN MANY COS THINK FLOOD WATCH IS GUD IDEA FOR MUCH OF AREA.
CDFNT MOVS SE OF CWA THIS EVE SO FAR NW SHUD BE DRY SO POPS THERE
NEED TO BE ADJUSTED DOWN ALG WITH PUTTING SOME TIMING IN FOR RMNG
PRECIP ENDING NW TO SE TNGT.

HI PRES AND DRIER AIR BLD IN FRI FOR DRY WX AND NOTICEABLY LESS
HUMID CONDS.

&&

.LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...
HIGH PRESSURE BUILDS SOUTHEAST ACROSS THE AREA FRIDAY NIGHT AND
PUSHES MOISTURE SOUTHEAST OF THE AREA.  THE HIGH DOMINATES THE
WEATHER THROUGH SUNDAY BUT A RETURN BACK TO TEMPERATURES IN THE
MIDDLE AND UPPER 80S IS EXPECTED AS RETURN SOUTHERLY FLOW DEVELOPS
ON SUNDAY.

WEAK COLD FRONT SHIFTS SOUTHEAST OVER THE AREA SUNDAY NIGHT.
MOISTURE WITH THE FRONT WILL BE LIMITED. HOWEVER...WILL KEEP MENTION
OF CHANCE OF SHOWERS AND THUNDERSTORMS SUNDAY NIGHT WITH THE FRONT.

ANOTHER DIRTY HIGH PRESSURE SYSTEM WILL BUILD SOUTHEAST ACROSS THE
AREA MONDAY NIGHT AND TUESDAY. THE HIGH WILL BRING WITH IT SOME
MOISTURE TO WORK WITH AND DAY TIME INSTABILITY COULD CAUSE A CHANCE
FOR LATE MORNING AND AFTERNOON SHOWERS AND THUNDERSTORMS TO
DEVELOP.

THEN MUCH DRIER AIR WILL WORK INTO THE AREA WEDNESDAY WITH THE HIGH
PRESSURE SYSTEM AS IT MOVES SOUTH OVER THE REGION.  SO WILL BRING AN
END TO THE SHOWER AND THUNDERSTORM THREAT.

STAYED FAIRLY CLOSE TO MEX GUIDANCE TEMPERATURES THROUGH THE PERIOD.

&&

.AVIATION(06Z-06Z)...
LEADING CONVECTION OVER FAR NRN INDIANA/SRN MI CONTINUES TO WEAKEN
AS THE ASSOCIATED COLD POOL OUTRUNS THE CONVECTION AND IT MOVES INTO
DRIER AIR OVER OHIO. THE FRONT OVER CENTRAL LOWER MI WL MOVE TO JUST
N OF TOL BY 12Z...THEN SLOW DOWN AS THE WAVE OVER MISSOURI MOVES
ALONG THE FRONT. THE FRONT WILL BE THE MAIN FOCUS FOR CONVECTION ON
THURSDAY. BY 18Z...THE FRONT SHOULD BE THRU TOL/CLE/ERI. THIS MAY
LIMIT THE STRENGTH OF CONVECTION FOR THESE SITES. HOWEVER...STRONGER
CONVECTION IS VERY POSSIBLE FOR THE SOUTHERN SITES BY AFTERNOON. DID
NOT WANT TO PIN DOWN DETAILS ON THE CONVECTION...BUT THE GENERAL
THINKING IS THAT THERE WILL BE NUMEROUS/WIDESPREAD STORMS THROUGHOUT
THE AFTERNOON ESPECIALLY FOR THE SOUTHERN 1/2 OF THE FORECAST AREA
WHERE THE BEST INSTABILITY WILL BE. SOME OF THE STORMS MAY BE STRONG
BY AFTERNOON WITH A SFC DELTA THETA-E OF -35C AND DCAPE OF 1500
J/KG. THIS WILL MAKE SEVERE WIND GUSTS OF 50 KT OR GREATER THAN MAIN
CONCERN WITH ANY SEVERE STORM.

OTHER THAN THE STORMS....MAY SEE A FEW SITES TEMPORARILY DROP TO
MVFR VSBYS BY 10Z. HOWEVER...SLIGHTLY STRONGER WIND AND BETTER
MIXING MAY SHOULD PRECLUDE VSBYS DROPPING TO IFR.
